Ext的Hello World

<link rel="stylesheet" type="text/css" href="resources/css/ext-all.css" />
<script type="text/javascript" src="adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="ext-all.js"></script>

<script>
Ext.onReady(function(){
    Ext.MessageBox.alert('helloworld', 'Hello World.');
});
</script>

 

注意:导入ext-base.js的位置一定要在导入ext-all.js之前
